[CLOSED] GridPanel: When I update a value in the store object I wish update the gridPanel

[supera]

Hi!

I wish when I update a value in store object, the value are update (reloaded?) in the GridPanel.

How I do this?

Thanks for any help!

Hi,

How do you change the Store data?

This way?

record.data.someField= "new value";

If yes, then you need to refresh the GridPanel View.

grid.getView().refresh();

Or you can use the record set method. It is the best when you need to set up just a single record field.

record.set("someField", "new value");

Or the beginEdit and endEdit methods for editing several record fields.

record.beginEdit();
record.data.soeField1 = "new value 1";
record.data.soeField2 = "new value 2";
record.endEdit();

The changes will be automatically refreshed in the grid.

If you change many records and many fields in the Store data, it would best to use the first approach.

Ok!

Thanks Daniil!

Hi you managed to get it work ? Where is the 'record' object from ?

[Daniil]

It can be retrieved from a Store.

var record = store.getAt(0);

Great.. this is working...

record.Set("xxx", 888)

I am doing this in OnBeforeStoreChanged, is this a good place ? FYI. I wish to do some calculations based on some tables in the DB.

[Daniil]

I would avoid such an operation in a OnBeforeStoreChanged handler.

The modified records should be returned in a response of a save request. Please see e.ResponseRecords here.

But I need to recalculate after changing the value in the cell..(based on some db rates/calculations), where is the best event for this ?

[Daniil]

You can change returned records as you need.

You can change returned records as you need.

Like this ?

protected void Store1_BeforeChanged(object sender, BeforeStoreChangedEventArgs e)
    {
        this.db = new NorthwindDataContext();
        this.responseRecords = new List<object>();
    }

I dont see what is this code doing. Perhaps I miss something ?

Thank you !!!
